Behavioral inhibition induced by ingestion in sea anemones (Anthopleura elegantissima)

Covering behavior in two intertidal anemones, Anthopleura elegantissima and Anthopleura xanthogrammica: Is it inducible in the lab?

Characterization of a novel EF-hand homologue, CnidEF, in the sea anemone Anthopleura elegantissima.

The superfamily of EF-hand proteins is comprised of a large and diverse group of proteins that contain one or more characteristic EF-hand calcium-binding domains. This study describes and characterizes a novel EF-hand cDNA, CnidEF, from the sea anemone Anthopleura elegantissima (Phylum Cnidaria, Class Anthozoa). CnidEF was found to contain two EF-hand motifs near the C-terminus of the deduced a...

Oxygen Radical Production in the Sea Anemone Anthopleura Elegantissima and Its Endosymbiotic Algae

Host animals in algal-invertebrate endosymbiotic associations are exposed to photosynthetically generated hyperoxia while in sunlight, conditions conducive to photodynamic excitations and production of cytotoxic oxygen-derived radicals such as the superoxide anion (O2 ) and the hydroxyl radical ('OH). All previous evidence of oxyradical production in symbiotic associations has been circumstanti...

Effects of social organization on inter-clonal dominance relationships in the sea anemone Anthopleura elegantissima

In the sea anemone Anthopleura elegantissima contact between non-clonemates often elicits inter-clonal fighting, involving the application of nematocyst-laden fighting tentacles (acrorhagi) and the locomotory retreat of losing polyps. This study confirms that isoclonal aggregations of A. elegantissima display an inducible polymorphism, such that polyps at the inter-clonal boundaries (warriors) ...

Biogeography of two species of Symbiodinium (Freudenthal) inhabiting the intertidal sea anemone Anthopleura elegantissima (Brandt).

We have analyzed the genetic profiles of dinoflagellate populations obtained from the Pacific coast sea anemone Anthopleura elegantissima (Brandt) at collection sites from Washington to California. Genetic differences within the symbiont populations of California anemones have been uncovered by restriction length polymorphism (RFLP) analysis of the small subunit (SSU) and large subunit (LSU) ri...
